How to make visible “your location” button and pointer in ionic?

In ionic app which is based on google map Api v3 . I want to make your location button withlocation pointer visible in app. is there any possible way?

Regarding to Google documentation
I add these lines to code but no result:

let mapOptions = {
        center: latLng,
        zoom: 15,
        MyLocationEnabled: true,
        setMyLocationButtonEnabled: true,
        zoomControl: false,
        disableDefaultUI: true,
        mapTypeId: google.maps.MapTypeId.ROADMAP,
